source: trunk/softs/tsar_boot/include/boot_utils.h @ 479

Last change on this file since 479 was 425, checked in by cfuguet, 11 years ago

Modifications in tsar_boot:

  • Creating new files boot_utils.[c h] containing the memcpy, memset and some ELF format debug functions
  • Introducing assert in the boot_elf_loader to show an error when some of segments to load conflicts with some of the pre-loader segments
  • Cosmetic changes in boot_elf_loader to improve code readibility
  • Fixing bug in dcache_buf_invalidate function used by boot_ioc_read when cache coherence not supported. The condition in the for loop was erroneous.
  • Modification in Makefile: The SYSCLK_FREQ parameter is not passed anymore

as a Makefile parameter but it is definesd in the defs_platform.h file
